IMPROVEMENT IN TORPEDO-BOATS Specification forming part of LettersPatent No. 202,453, dated April 16, 1878; application filed January 28,1878.

To all whom it may concern:

Be it known that I, HANS MoRTENsnN, of Alma, in the county of Park andState of Colorado, have invented a new and Improved Torpedo-Boat, ofwhich the following is a specification Figure 1 is a longitudinalsection of my improved torpedo-boat. Fig. 2 is a plan view with the topremoved. Fig. 3 is an inverted plan view of the top of the boat. Figs. 4and 5 are detail sectional views of the valve connected with thespar-cylinder.

The invention will first be described in connectionwith the drawing, andthen pointed out in the claims.

Similar letters of reference indicate corresponding parts.

Referring to the drawing, A is the hull of the boat, which has anarc-shaped keel, B, that runs the entire length of the boat and projectsbeyond the stern. A portion of the keel is cut away at the stern toreceive the rudder O, which is pivoted in the support thus formed. Therudder is provided with two arms, a, one on each side, that project atright angles to the face of the rudder, to receive the thrusts of thescrew-rods b, which project through the stern of the boat, one on eachside of the keel. The hull of the boat is divided into severalcompartments.

The compartment 0 is designed to contain the men that operate thetorpedoprojecting mechanism. The compartment (1 contains the men whointroduce the torpedo into the projecting apparatus and attach it to themovable rod. Upon each side of the compartment d there are compartments0 for containing either air or water, as occasion may require, saidcompartments being connected with each other under the compartment d bya passage, e. They are also connected with the compartment d by passages01 closed by doors d Above the compartment 0 there is a chamber, f,which contains compressed air for the supply of the crew and working themachinery. Under the compartments e c b there is a compartment, f, forcontaining water forced in against an air-cushion. The chamber thus actsas an accumulator of power which is expended in working thetorpedo-projectin g ap-' paratus.

A cylinder, D, containing the piston h and piston-rod i, is placedlongitudinally in the hull, and is provided with the loadingchamber j,which projects through the bow of the boat, and is provided with aloadin g-a'perture, k, which is closed by a hinged and tracked cover, Z.

Below the loading-aperture In there is a chamber, m, which contains avalve, n, that is forced upward into the loading-chamber j to excludethe water while the torpedo is being attached to the piston-rod i. Theloadingchamber j communicates with the chamber m through an aperture, 0,which is stopped by the valve 9. This aperture is for the escape to thechamber m of any water that may leak into the loading-chamber j duringthe operation of loading. The cylinder D is provided with a rotaryvalve, g, which communicates with the ends of the cylinder D by pipeso", and is connected with the accumulator-chamber f by means of thesupply-pipe o and with c an escape-pipe, s. This valve is provided witha right-an gled passage, t, which may be turned so as to bring either ofthe pipes 03 into communication with the supply-pipe o. It is alsoprovided with the passage u, that communicates with either of the pipesr and with the escape-pipe s, so that water under pressure may beadmitted or permitted to escape irom either end of the cylinder, so asto project the piston-rod i and explode a torpedo by contact with avessel or retract the piston, as may be required.

The water required for working the piston may be forced into the chamberf before the boat is started, or it may be forced in by hand orotherwise while the boat is under way.

The rods 12, by which the rudder is operated, are threaded, one beingprovided with a righthand and the other with a left-hand thread, andwork in fixed nuts, and are provided with spur-wheels a, which mesh intoa driving spur-wheel, that is driven by a suitable motor or by hand.

The boat is covered by a removable upper portion, E, which is similar inform to the hull, and is secured to the hull by means of bolts, and awatertight joint is made by'means of calking or packing.

The top is comparted in the same manner as the hull, and'both top andhull are provided with suitable valves a b for the admission and escapeof air and water. There is a'passage, a between the room 0 and thesternroom I).

In the top there are two entrances, c (1, provided with hinged covers 0f, which are packed to render them water-tight.

The compartments for containing the crew are provided with suitablewindows, which open inwardly, so that they may be repaired or replacedin case of breakage.

In each side of the boat there are recesses g h, which are inclined inopposite directions. In each of these recesses a screw-propeller, i, isplaced, the shaft of which extends into the boat, and is connected witha suitable motor.

By means of these screws the boat may be propelled forward or backward,and raised or lowered, as may be required.

The boat is capable of being operated wholly under the water; or the topportion'may -be removed, when it may be propelled on the surface.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Pate'nt- 1. The combination, with hull A, of the keelB, extending its whole length, projecting at the stern, and havingrudder pivoted therein,'as and for the-purpose described.

2. In a torpedo-boat, a cylinder, D, having valve q, with the passages12 w and pipes r, in combination with the chamber f, connected therewithby pipes, as and for the purpose specified.

'3. The combination of the water-escape valve 19 with the chamber j,having the discharge-opening 0, substantially as shown and described.

4. The combination of the screw-rods b with the rudder 0,-having armsa,-'substantiallyas herein shown'and-des'cribed.

HANS MORTENSEN.
